About 20 years ago, the Des Moines police got a call about a guy wandering a neighborhood street, waving a butcher knife and talking crazy.

They responded to the scene and found the guy. After repeated orders for the guy to put down the knife, the guy charged one cop, knocked him down and began stabbing him in the chest. Fortunately, the cop had on a bullet-proof vest which offered some protection, so he was not seriously injured. He did, however, pull his service revolver and blew the guy away as he was stabbing him. The guy died on the scene.

A day or so later, the guy's mom was whining to the press about how "They didn't have to kill my baby!"

WTF? He's doing his damnedest to kill the cop and the cop had every damn right in the world to blow his farking head off in self-defense. Even the ACLU told mom to STFU.
